Pull more mount API conversions from Al Viro:
 "Assorted conversions of options parsing to new API.

  gfs2 is probably the most serious one here; the rest is trivial stuff.

  Other things in what used to be #work.mount are going to wait for the
  next cycle (and preferably go via git trees of the filesystems
  involved)"

* 'work.mount3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  gfs2: Convert gfs2 to fs_context
  vfs: Convert spufs to use the new mount API
  vfs: Convert hypfs to use the new mount API
  hypfs: Fix error number left in struct pointer member
  vfs: Convert functionfs to use the new mount API
  vfs: Convert bpf to use the new mount API
